Angular 停止 Router NavigationStart

Question

是否可以在 Angular 中停止 NavigationStart？如果用户尝试更改路线，我会尝试提示自定义确认模式。

constructor(private router: Router) {
    if(val instanceof NavigationStart){
        //prompt the confirmation modal and stop NavigationStart or at least 
          make it wait until user performs any action
    }
}

Answer 1

您可以防止路由被解析为 CanActivate or CanDeactive class
